Recent articles in Mlive Ann Arbor News about the growing dioxane plume have raised some questions from residents about the safety of our drinking water in Loch Alpine. The Gelman/Pall dioxane plume epicenter is at the Gelman/Pall location on Wagner Road, south of Jackson Road, and has been slowly expanding predominately eastward into Ann Arbor. According to LASA, the plume is not a threat to Loch Alpine drinking water because the aquifer that feeds the LASA wells flows from the northwest of the neighborhood, the opposite direction from the plume.
